Power Connection

Electrocution or fire may occur if machine is ungrounded, incorrectly connected to power, or connected to an undersized circuit. Use a qualified electrician to ensure a safe power connection.

Once your machine is set up and assembled as previously described in this manual, it is ready to be connected to the power source.

Use the information in this section to determine the power source requirements needed to operate this machine. If your existing power source does not meet the stated requirements, consult with a qualified electrician about running a new circuit.

Note About Extension Cords: Using an incorrectly sized extension cord may decrease the life of electrical components on your machine.

Note About 3-Phase Power (SB1041 Only): DO NOT use a static phase converter to create

3-phase power—it can quickly decrease the life of electrical components on your machine. If you must use a phase converter, only use a rotary phase converter and connect the wild wire to the correct power connection terminal, shown in the wiring diagram on Page 53.

220V Conversion for SB1040

Wiring diagrams are provided on Pages 50 and 52 in this manual, showing the Model SB1040 wired for both 110V and 220V. Refer to these diagrams when following this procedure.

To convert the Model SB1040 to operate on 220V:

1.DISCONNECT BANDSAW FROM POWER!

2.Rewire the motor for 220V, as shown in the diagram on the inside of the motor junction box. If there is not a diagram in the junction box, use the motor wiring diagram in this manual (see Page 52).

3.Locate the power transformer in the electrical panel (see Figure 56 on Page

54). Remove the wire attached to the 110V terminal and connect it to the 220V terminal.

4.Turn the dial on the overload relay (see Figure 56 on Page 54) from 14A for 110V to 7A for 220V.

5.Locate the welding transformer in the control panel (see Figure 55 on Page

54). Remove the wire connected to the #2 terminal and move it to the #5 terminal; remove the wire connected to the #4 terminal and move it to the #7 terminal. The machine is now wired for 220V.

Correcting Phase Polarity (SB1041 Only)

This sub-section is only provided for troubleshooting 3-phase power connections. If you discover during the test run that the machine will not operate, or that the motor runs backwards, the power source connection may be wired "out of phase," meaning that the polarity is incorrect as wired. Without test equipment to determine polarity, this is a common situation with 3-phase power.

To correct the polarity of a power source connection:

1.DISCONNECT MACHINE FROM POWER!

2.Open the electrical box and disconnect the incoming power cord R and T wires from the main terminal bar in the upper right corner of the electrical panel (see Page 53).

3.Connect the R wire to the terminal where the T wire was connected originally.

4.Connect the T wire to the terminal where the R wire was connected originally.

5.Close and latch the electrical box, and reconnect the machine to the power source.

6.Follow the Test Run on Page 21 to ensure that the machine functions properly.
